I must very much disagree. The suits in The Dark Knight were a disaster. Low gorge, windsor/half windsor knots, gap between the lapels and collar in almost every shot. The scene where he gives the speech in the penthouse before the Joker shows up I remember being mesmerized by how poorly the fit was on the jacket considering how much advertising Armani did to highlight the fact he was wearing their suits.

Even in the pictures you posted there is gap, and the pants look to be pleated.

Also, look at all the ripples and fold on that suit, just from standing still. was there a single ripple on the duke of windsor's whole outfit? No.

The backs of the suits are completely pulling, I agree, it was a mess. I was 17 at the time when I saw it, and I myself was still amazed by how terrible they looked. I was even disappointed because I WANTED wayne to be well dressed, but we wasn't.
